All in JavaScript. Though JavaScript based, there's asm.js optimizations and the performance seems to be quite decent in modern web-browsers. The jor1k OpenRISC emulator can do a lot even handle running the Linux kernel, GCC compiler, ScummVM Monkey Island, and the Wayland/Weston Compositor all from within the web-browserLink to Original Source
